(Merlin using Garden of Avalon)

The Reverse Side of the World in Fate/Grand Order.

The Reverse Side of the World (世界の裏側, Sekai no Uragawa?) is the layer of the World that retains the laws of the Age of Gods, housing surviving Phantasmal Species instead of people.

Also known as the inner sea of the planet (星の内海?), it is the place where the soul of the World is kept.[1]


The world where humans currently live employing the laws of physics is like a fabric that thinly extends across the surface of the planet, and underneath this fabric exists the Reverse Side of the World, where supernatural beings have retreated to after the Age of Gods ended. Finally, beneath that fabric exists the planet known as "Earth". In other words, the Earth is the bottom layer of the planet, and it is covered by the “Reverse Side of the World” — the place where the laws of the "World" as it once was reigns, and covering that is the "Present World" where humans of the Age of Man live.[2] It is located 2700 kilometers below the surface.[3]

Rhongomyniad is one of the "anchors" that fasten the planet together to ensure that the world of humans on the outermost layer of the world can't be destroyed by those on the Reverse Side who wish to reenact the Age of Gods. The Holy Spear that King Arthur holds is nothing more than a shadow of the main body: a tower that fastens together the skin of the world. It exists to be the planet's anchor and to ensure the World's stability.[4][5]

The highest class of fairies, known as Great Fathers or Great Mothers, are born in the Reverse Side of the World and can be thought of as Divided Spirits of the planet's soul. They're about the same scope as an anthropomorphized nature divinity, but unlike those gods, they are not clothed in human rules. Great Fathers and Mothers are pure transcendent existences. Morgan le Fay/Vivian is an example of a Great Mother fairy.[6] Excalibur was also created here.[7]

The Spiritual Tomb of Albion beneath the Clock Tower in London is a massive underground labyrinth that gets near to the Reverse Side, though does not quite reach it as the dragon that was digging the tomb died before it could finish.[8]


For the specific Noble Phantasm, see Avalon.

AvalonWP (アヴァロン, Avaron?) is the paradise in the Arthurian legends, existing in the Reverse Side of the World at the same coordinates as Britain. It is a small world that was called the Land of the Eternal Spring and the Island of ApplesWP in mythology, the utopia was thought to be derived from the island that produced the "Apple of Immortality" in Greek mythology.[9] King Arthur is said to dwell in Avalon and will eventually return to lead England to true glory.[10]

It is a Utopia that may not be granted to beasts which possess wisdom, one that may never be reached. It is a world cut off from the constant decay and destruction of the surface of the planet and, although it is nestled in human history, has no connection to other lands at all. Daytime is filled with spring’s sunshine and the smell of summer; night is wrapped in the autumn air and stars of winter. It is where flowers of all colours bloom on gently sloping plains. A forest can be clearly seen in the far distance, enveloped by the overlooking sky; the view is evenly divided between the sky and the earth. There is no sign of human civilization in the lands. On earth there are countless flowers and bugs; in the forest there is water and green, and ethereally beautiful fairies lurk in the pond. The paradise people imagine is only an imitation of this place. Here, in this un-trodden place, the bounds of a tabooed land (禁足地, kinsoku-chi?) serve as the ends of the island. Though the island has no end, it seems to change like any other land. Further into the island the land turns barren, similar to Britain. It is where fairies got up and went to after the Age of Gods ended.

According to Merlin, the density of magical energy in Avalon is too strong for a human to handle. He thought it should not be called a paradise, but it could be better utilized as a weapon instead. He compares the place to a vacuum, simply breathing in it is enough to end up dead. In one breath a human of the current age would burst from inside out.[11]

The Tower of Avalon (最果ての塔, Saihate no tō?) in Fate/Grand Order.

Merlin came to Avalon near the end of King Arthur's reign while running from an angry Vivian, only to be imprisoned in a tower by her. Unable to die until the end of the world, Merlin remains trapped in his tower even into the 21st century.[11] Due to unknown events, the Merlin of the Fate/Prototype universe is no longer confined in the tower of Avalon.[12]


Fate/stay night[]

Once Artoria Pendragon terminated her contract with the World by destroying the Holy Grail by her own will, she goes to Avalon. In the Last Episode, Shirou Emiya was able to reach Avalon and reunite with Artoria.


Jeanne and Fafnir (Sieg) reunite in the Reverse Side.

Sieg in his Fafnir dragon form migrates the Greater Grail to the Reverse Side of the World. In the Reverse Side of the World, the Holy Grail cannot activate Amakusa Shirou Tokisada's wish of "Salvation of mankind through the Third Magic" simply because no humans exist there.

Reaching the Reverse Side of the World as a Heroic Spirit is not impossible because Heroic Spirits have already become inhuman the moment they died; however, the probability is incredibly close to zero. In order to reach the Reverse Side to reunite with Sieg, Jeanne d’Arc essentially tried an infinite number of times from the Throne of Heroes, which was removed from the time axis. It took her a long, long time, but she eventually succeeded.[2]

Garden of Avalon[]

Merlin throws out Fou.

While Merlin was imprisoned within the Garden of Avalon, he went through the drafts and sketches he had made in life and started telling Cath Palug the events of the life of King Arthur.[13]

Upon witnessing Arthur's final moments, Merlin releases Cath Palug from the Garden of Avalon, insisting that he seek out "that which is beautiful."[14]

Fate/Grand Order[]

Camelot: Divine Realm of the Round Table[]

Bedivere reached Avalon after wandering for centuries unable to die, where he met Merlin and was sent to the Camelot Singularity.[15]

Apocrypha: Inheritance of Glory[]

Sieg as Fafnir, still waiting for his reunion with Jeanne, calls Ritsuka Fujimaru's consciousness into the Reverse Side of the World to help him deal with a problem occurring in the Greater Grail.

Avalon le Fae: Fae Round Table Domain[]

Merlin contacts Fujimaru from his prison in Avalon and tells them of a prophecy concerning the English Lostbelt, then says that he will be watching from within his tower until they can meet again after the battle.

Later, on the advice of Merlin, Artoria and her companions travel to Avalon via the Spiritual Tomb of Albion in order to forge Excalibur. Merlin refers to this Avalon as a "shadow" that the Lostbelt has taken in, unaffected by the bleaching of the world.


Manaka Sajyou sees Sieg as Fafnir waiting for Jeanne when she sends her consciousness through the Reverse Side of the World.[16]


Arthur Pendragon reached Avalon at some point after the Second Grail War, but was informed by Merlin that he could not enter it until Beast VI was destroyed for good.

Lord El-Melloi II Case Files[]

Kurou Adashino fell from the Spiritual Tomb of Albion into the world of fairies when he was young, and while there had his heart stolen by fairies. When he found an exit he discovered that he had gone back in time as fairyland was outside of time and space.

The efforts of Trevor Pelham Codrington to create artificial Black Dogs eventually led to a gate to the fairy realm opening on his estate as the dogs called for more of their kind to form the Wild Hunt. The gate closed soon after, when Wills Pelham Codrington passed through to be with his love Faye.[17]

Gray's hometown Blackmore Cemetery has a secret underground temple which is designed as a replica of Avalon. It is here where the ritual to turn Gray into Artoria was planned to take place.[18]

    Reverse Side of the World [Others]
    The place where the evil dragon Fafnir finally arrived at the very end of the novels. The Phantasmal Races, having understood that the Age of the Gods was over, ceded the Earth’s surface to humans and moved to this place. The world where humans currently live (including the laws of physics) is like a fabric that thinly extends across the surface of the planet. Beneath that fabric exist the planet known as “Earth”. On the other hand, the Reverse Side of the World is the world as it was before humans lived there… that is, the fabric of the era where Phantasmal Races strode the land. In other words, the Earth is the bottommost layer of the planet, and it is covered by the “Reverse Side of the World”—the place where the laws of the “world” as it once was reigns, and covering that is the “Present World”.
    In the Reverse Side of the World, the Holy Grail cannot activate its function of “using the Third Sorcery”. In the first place, that function was for the sake of granting Shirou Kotomine’s wish. In other words, it is programmed to target humans, and doesn’t count Phantasmal Races as valid targets.
    Jeanne d’Arc is a Heroic Spirit who, from the start, lost her human body long ago. Because of that, the chances of her reaching the Reverse Side weren’t completely zero… However, that is merely the kind of “not zero” like, as a comparison, somehow managing to pass through a wall with the tunnel effect, but the Throne where Heroic Spirits Exist is cut off from the time axis, so she effectively had an infinite number of attempts to try.

    The Everdistant Utopia [Noble Phantasm]
    The paradise in the Arthurian legends; a scabbard bearing the name of the Faerie Land.
    The utopia Avalon was thought to be derived from the island that produced the "Apple of Immortality" in Greek mythology.
    Avalon mended all wounds and halted the wielder's aging process. After unleashing its true name, Avalon would break into hundreds of shards and shield the wielder from all interference.
    The sheath of the holy sword was excavated by the Einzberns from Cornwall. It was given to Kiritsugu as a catalyst to summon King Arthur.
    It was a Noble Phantasm reaching the realm of True Magic. Avalon shut out all physical interference, operation of parallel worlds, and multi-dimensional communication (up to the sixth dimension).
    If Saber went hikikomori, no one would reach her.

  10. [v] Fate/EXTRA - Francis Drake (Rider) Matrix [T]

    Class: Rider
    Master: Shinji Matou
    True Name: Francis Drake
    Noble Phantasm: Hunt of the Golden Hind: Golden Stag and the Eventide Tempest
    Keyword: Invincible Armada, Logbook
    Strength: D, Defense: C, Agility: B, Magic: E, Luck: EX
    Anti-Magic: D, Rider on the Storm: A+, Settler of the Stars: EX


    01 - Hunt of the Golden Hind: Golden Stag and the Eventide Tempest
    This Noble Phantasm is Rider's ace in the hole and forms the basis of her day-to-day life. With her flagship, The Golden Hind, at the fore, a vast flotilla of smaller craft expand ever outward and exterminates her enemies with overwhelming firepower. Its attributes contain vestiges of not only the fleet that eventually defeated the mighty Spanish Armada, but also of the stories involving the golden stag and the eventide tempest that had spread throughout the whole of Europe.

    The eventide tempest is the encapsulation of all storms, from blizzards to cyclones, which manifest in the imagination of men as beasts and soldiers, saviors and monsters. Depending on who is speaking, the leader of these apparitions ranges from a fallen King Arthur to the Norse god Odin to the first murderer of men, Cain. in England, it is believed that Francis Drake rides the endless storm despite the fact that the role assigned to her is usually given to malevolent figures of history and myth.

    02 - Invincible Armada
    The name given to the Spanish naval forces during the period of history known as the Age of Discovery.

    The Invincible Armada consisted of an estimated 65,000 men serving on more than a hundred large warships, each of which weighed in at over 1,000 tons. Its might was such that it earned Spain the reputation of being "The kingdom on which the sun will never set."

    03 - Logbook
    The sailing logs of a renowned explorer who successfully circumnavigated the globe.

    The logs themselves are illegible, with pages cracked and flaking. However, it seems that the author of these logs was a ship's captain who made their name as both an adventurer and fleet commander.

    Anti-Magic [D]
    Cancels single-action spells.
    It also bestows magical resistance equal to that normally provided by a physical talisman such as an amulet.

    Rider on the Storm [A+]
    Talent that lets one sail objects recognized as ships.
    As the ability to lead is essential in her position, this unique skill also has an effect on Charisma and Military Tactics.

    Settler of the Stars [EX]
    This unique ability is given to those heroes whose exploits became turning points in human history.
    Any difficult voyage and insurmountable challenge cease to be "impossible" and became "events to be realized."





    01 - Character Background
    The person who circumnavigated the globe and paved the way for England to become the dominate superpower in the Age of Discovery through its substantial earnings. This person was also the one who was given credit for the virtual destruction of Spain's Invincible Armada, which caused the nation once thought of as "the kingdom on which the sun will never set" to teeter on the edge of collapse.

    She is a person who has dedicated her life to hedonistic pursuits and sees no difference between a paragon of virtue and a rogue scoundrel. She revels in all things gaudy, whether they are in war or in her private life, and is content to chase after ephemeral pleasures and leave nothing of worth behind, much like the passing of a raging storm.

    She is particularly entranced with treasures of gold and silver, but her true love lies not with enduring treasure, but those treasures that explode like fireworks and then quickly fade away.

    As she so often declares, "I chase after gold so that I can scatter it like a storm!"

    It is for this reason that she is wholly incompatible with the Hero of Legend that symbolizes "an inexhaustible treasury." She would also be at odds with the fox-eared Caster, as Caster is the epitome of eternity.

    As a devoted libertine, all that matters to her is the inevitable crash at the end of it all. A Legendary Spirit who is completely indifferent to the frailty of human existence, she is content to indulge in her own whims and desires until death comes to greet her.

    She died of dysentery at the age of 55. Her dying wish was that she be buried in her full armor.

    02 - "Franciscus Draco"
    Sir Francis Drake is generally considered the first person to successfully circumnavigate the globe (the first person known to have attempted this feat -- Ferdinand Magellan -- was killed halfway through his voyage).

    Though a male in life, Francis Drake has materialized in Fate/EXTRA as a woman.

    During the time of Francis Drake, England was considered to be a second-rate power with no real influence beyond its borders and no colonies of worth overseas. It was primarily due to his voyages and successes on the high seas that gave rise to the British Empire. The combination of the wealth he brought to the country and the detailed maps he produced while circumnavigating the globe allowed Britain to assemble a fleet that rivaled that of Spain's.

    An oft-mentioned aspect of the Drake mythos is that of his ship, the Golden Hind. Not only was it the flagship of Drake's fleet, it was seen as a symbol of hope and a source of miracles. The exploits the Golden Hind made possible elevated Drake (known and feared by the Spanish as El Draque) to a level on par with King Arthur. Both are said to dwell in Avalon and "across the ocean", the city of the dead, and will eventually return to lead England to true glory.

    During what was to be the final confrontation between England and Spain's Invincible Armada, Francis Drake was commissioned as a vice admiral in the English navy. Using an unorthodox strategy involving the use of fire-ships, he forced the Spanish fleet into open water where they could be bombarded with cannon fire.

    In addition - and this is merely literary creation - there is also a story full of romance in which Drake was a companion of Queen Elizabeth and, just before setting sail for the world circumnavigation, switched places with the Queen, who could no longer go out in public due to receiving a wound on her face.
